Foam at the shore of a lake, caused by pollution from nearby agriculture. Run-off of fertiliser leads to eutrophication, the massive overgrowth of algae at the expense of other plants. The algae are decomposed by bacteria, which takes oxygen from the water and releases organic material that can cause foaming. Filmed in Denmark. | |
